X-Git-Tag: v3.9-rc1~97^2~66 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f379aae558b8daff0f7a1c5fc225af5d35c741f7;p=pandora-kernel.git KVM: s390: In-kernel handling of I/O instructions. Explicitely catch all channel I/O related instructions intercepts in the kernel and set condition code 3 for them. This paves the way for properly handling these instructions later on. Note: This is not architecture compliant (the previous code wasn't either) since setting cc 3 is not the correct thing to do for some of these instructions. For Linux guests, however, it still has the intended effect of stopping css probing.
